Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 b12 does not exactly " pool " ; any excess is excreted in urine. However it IS possible to have " tissue vitamin b12 deficiency " . " serum vitamin B12 level as the sole means of diagnosis may miss up to one half of patients with actual tissue B12 deficiency. " and " A more sensitive method of screening for vitamin B12 deficiency is measurement of serum methylmalonic acid and homocysteine levels " from: http://www.aafp.org/afp/2003/0301/p979.html It can't hurt to track down any b12 problems. If it were me, however, I would not limit my search to b12 issues only, because shortness of breath and rapid pulse can have other causes. > > Is it possible for b12 to pool in the blood and not get adequate amounts to the cells? > > My last blood test for b12 and folate showed high, just over top range.

Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 I can't answer your question. Although, I had a b12 deficiency, and I tried sublingual b12, and I was still having fatigue problems. I started taking methylcobalamin b12 injections, and boy did that make a difference. I could tell a diffence for sure.

Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 A B-12 deficiency seems to cause t3 to pool. About a month ago, i started taking 15-20,000 sublingual B-12 and I had a dump that lasted 10 days. Temps in the 99's and I had to lower t3...I felt great. I am starting methyl shots hopefully this week. > > Is it possible for b12 to pool in the blood and not get adequate amounts to the cells? > > My last blood test for b12 and folate showed high, just over top range.

Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 Hi all, I would add that after you start supplementing B12, the MMa (methylmelonic acid) test becomes much less helpful as this acid goes right down as soon as your start. The homocysteine goes down too. A good way to judge how well your body is recovering from B12 deficiency is looking at the MCV (mean corpuscular volume) done as a part of a CBC test. If you'd been deficient for long enough, your MCV goes high, and you have macrocytic anemia. Aim for an MCV in the range of 90. Ninety-four to 96 is indicative of macrocytic anemia, 96 - 100 you've got it, and 100 and above, yessiree! Pam Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 Hi, Some people don't metabolize B12 properly, either from food or supplements. Also, only a fraction of the B2 supp you take actually gets into the cells. So, yes, your serum level can look way, way good, and your body can still be in process of replenishing its supplies. What little B12 your body needs and gets is recirculated a great deal. So, it can take a long time, months and even years, do become depleted at the cellular level. As others have mentioned, the methylcobalamin shot is the best way to bring your cellular level up. Sublinguals are better that swallowed supps.

Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 > As others have mentioned, the methylcobalamin shot is the best > way to bring your cellular level up. Are these available without a prescription? My last B12 test came back high above range, but that was almost a year and a half ago. I should probably recheck my levels. ~Rainbow~ 30 year old Female 5'6 " 139lbs Dx: Hashi's, AF, Wheat Sensitivity Rx/OTC: Cynomel 68.75mcg, HC 22.5mg, Florinef 1tab, Potassium 90mEq, Sea Salt 3/4tsp My Log and Labs: http://tinyurl.com/pvgjmb My Blog: http://hyporainbow.wordpress.com Quote Link to comment Share on other sites More sharing options...
Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 B12 shots aren't available without a prescription in the US, as far as I know. Maybe you could ask whatever doctor diagnosed you with wheat sensitivity to prescribe it. You can easily inject yourself...tiny needle, slight subcutaneous jab.

Guest guest Posted June 15, 2010 Report Share Posted June 15, 2010 I'm afraid I no longer trust that doctor He tried to use muscle testing to get me to buy all kinds of herbal parasite remedies that did nothing. He wouldn't increase my meds when they needed increasing and he wouldn't prescribe me Florinef when I needed it.
